Sources said that during the bash on Rivington and Ludlow streets — where happy guests included Alec Baldwin and wife Hilaria — a woman appeared on top of a building across the street in an apparent suicide attempt.

Guests rushed outside to gawk, but Jokic managed to run to the top of the building, where another man “who appeared out of it,” spies said, “was begging her not to jump. Goran was able to grab her and pull her to safety.”

Jokic said he figured that, had she succeeded, “the opening would’ve been ruined. I had to save her!”
